      Playtest baseline. Surface + hidden 1..k deal; available 6/9/12;
      thresholds 5/7/9. Stress ledger has no problem pressure; ATTACK

      Ship-default. RPT-0003 + CB-EV-0031: under non-attacking competent
      policies, peak Stress held never exceeds start 2 — ATTACK is the
      sole inbound pressure. Keep pinned until a successor is accepted.

      Two deltas only: (A) +1 Stress each player at Round End if any
      Problem remains unclaimed; (B) uncancelled ACT_ATTACK by a seat
      at Stress ≥4 gives that seat −1 Stress. Thresholds/deal unchanged.

      Measured 2026-08-08 (CB-EV-0030/0031; instrument caveat applies).
      Direction right, magnitude wrong: H1-A is a solve-rate tax that
      competent seats absorb with GROUND (Stress ~3); H1-B never fires
      for them. DARVO arms for unregulated seats; group wins collapse
      to 0 at 3p+ under greedy SHARED GROUND. Do not promote as-is.
    decision: reject-as-baseline
    # Package stays selectable for regression compare; not a ship pin.

      Kernel implements H1-A/H1-B. Keep for A/B against successors (H2…).

    summary: >
      Unclaimed Problems apply +1 End Stress only to stress_scope:
      personal=owner, bond=owner's Bond network, global=all. Surface
      global; priority 3 is bond (in play at 3p+). Anyone may SOLVE any
      card. Not stacked on H1; no ATTACK self-soothe.

      better than H1; bond cards create joint SOLVE incentive in networks.

      Implement rules_delta H2-SCOPE, H2-OWN, H2-A, H2-SOLVE on base r0.
      Do not also apply H1 deltas. Problems.csv adds stress_scope column.
      Report bond-card SOLVE rates and stress variance vs r0 and h1.
